Application November 13, 1946, Serial No. 709,454

1 Claim. 1

This invention relates generally to punches, and more particularly to apunch having a resilient handle or hand grip portion compressed betweena head member and a nut threaclably engaged on the shaft of the punch.

An object of this invention is to provide a punch with a handleconstructed so as to provide an absolutely firm grip or steadying memberbut having this hand grip slightly resilient or compressible so that thejar imparted to the shaft of the punch is transmitted to the hand of theoperator in greatly reduced form.

Another object of this invention is to provide a punch with a handlewhich is of such size, shape and weight, and with this weight soproportioned and distributed as to make this tool at once safe andconvenient to use.

And a last object to be specifically mentioned is to provide a punchwhich will fulfill the objects mentioned above without detracting fromthe feel of the punch, when used for the purpose for which this punch isparticularly designed, namely, the application of rubber heels to bootsand shoes by shoe repairmen.

With these and other objects in view as will appear hereinafter, thisinvention consists of certain novel features of construction,combination and arrangement of parts as will be hereinafter described indetail and particularly set forth in the appended claim, reference beinghad to the accompanying drawings which form a material part of thisapplication, and in which:

Figure 1 is a perspective View of the assembled punch;

Figure 2 is a sectional view of the punch with parts being shown inelevation, to amplify the illustration of this invention; and

Figure 3 is a bottom plan view of the assembled punch.

Similar characters of reference refer to similar or identical partsthroughout the several views of the drawing.

As shown in the drawings, this invention includes a cylindrical shaftIll having an enlarged head portion l2 and a medial portion l4 screwthreaded. The working face of the shaft It] may be countersunk asindicated at l6, and the portion between said working face I6 and thethreaded portion l4 may be tapered as at l8.

The construction of the handle portion will now be described in detail.A metallic washer 20 is placed on the shaft H) to abut the head l2 and aleather covered metal washer 22 and a plurality of differentially sizedwashers 24 are placed side by side on the shaft with graduallydiminishing sized washers being placed toward the end [6 of the tool.Another plain metal washer 26 is then inserted, with a lock washer 28,and a nut 30 is then screwed tightly onto the threaded portion M of theshaft to hold the above mentioned transversely disposed memberscompressed together. The washers 24 may be either metal or of a somewhatcompressible material such as leather, and after the nut 30 has beentightened on the assembled transverse members, the assembly may beturned in a lathe or otherwise operated on to provide a smooth profile,and a handle will thereafter assume the appearance indicated in thedrawings. It is preferred for some uses to cover the built up portion ofthe handle with a single layer of compressible material such as leather,as indicated at 32, in Figure 2, the ends of the leather covering 32being simply turned under the washers 22 and 26 before the nut 30 isfinally tightened on the assembly.

The operation of this device is essentially that of an ordinary punchbut it may be noted that this punch is particularly well adapted forsuch uses as the application of rubber heels to shoes, an operationwherein a single stroke of the hammer is followed by a shifting of thepunch into a new position, and since such shifting of the punch is doneat great speed the safety features of this punch for such a use becomeof paramount importance. Other and various uses of this device willoccur to those who normally use small punches of this character.

The advantages of this invention will be obvious when consideration ishad to the structural details described above, but in recapitulation, itmay be noted that the handle portion is relatively large and slightlycompressible so that the punch will not easily slip out of the hand ofthe user, and the shape and resilient character of this handle greatlyincreases the safety with which the device can be handled quickly,without any lack of feel or diminished vision of the work operated upon.

Though there has been shown a particular embodiment of this invention,this application is not limited to this particular embodiment but it isdesired to include in the scope of the invention the construction,combination and arrangement of parts substantially as set forth in theappended claim.

Having thus described this invention what is claimed as new and desiredto be secured by Letters Patent is:
